摘要： An optical rate sensor (200) is disclosed for use in inertial reference systems to measure rates of angular rotation with substantially high resolution and sensitivity. The sensor (200) comprises a passive ring Sagnac interferometer (201) with a multiturn fiber optic ring (232) through which counter-propagating optical waves are transmitted. A nonreciprocal time variant phase modulation is applied to the waves along with periodic effective transposition of ring ports. The waves are combined to produce a "zero order" fringe pattern having an intensity varying in accordance with the relative phase between the counter-propagating waves. An intensity signal is derived from the fringe pattern having a phase offset corresponding to the Sagnac induced phase shift which in turn is linearly proportional to the angular rotation rate of the passive ring. Sampling, averaging and estimation circuits detemine the offset by detecting zero-crossing locations of the signal.

摘要： A fiber optic sensor coil is wound from a length of optical fiber with the mid-point of the optical fiber at the mid-point of the innermost layer of the coil and subsequent layers of the coil each have alternating turns of the two sections of the fiber emanating from the mid-point. The layers of alternating turns are formed by first winding a portion of one segment in such a fashion that adjacent turns are spaced apart by a distance equivalent to the diameter of the optical fiber. The layer is completed by winding a portion of the other segment such that the turns of the other segment are disposed between adjacent turns of the one segment. The number of turns in adjacent layers are unequal such that the turns of a next layer are arranged in grooves formed between two adjacent turns of optical fiber in the previous layer.

摘要： A force detecting microsensor comprises a single crystal Si substrate, a single crystal cone formed on the substrate and a resilient electrode mounted above the tip of the Si cone. The space between the tip of the Si cone and the resilient electrode is maintained in a vacuum environment and the distance between the tip and the resilient anode is in the order of a few atomic diameters. The tunneling effect of electrons occurs between the tip of the Si cone and the resilient electrode when a potential is applied to the resilient electrode and the Si cone tip. The resilient electrode deflects as a result of the force acting on the microsensor. The deflection of the resilient electrode alters the electrical characteristics between the resilient electrode and the Si cone tip. The changes in the electrical characteristics can be measured to determine the level of force acting on the microsensor. The process for making the microsensor according to the invention comprises the steps of forming an insulating layer and support layer on the substrate, forming a recess in the insulating layer and aperture in the support layer, depositing a single crystal Si cone on the substrate and fully enclosing the Si cone within the recess of the support layer and the insulating layer.

摘要： An optical rotation sensor comprises a light amplification stimulated emission ring laser formed in a solid medium is provided with phase modulator devices which produce push-pull phase modulation of counterpropagating optical waves in the ring thereby enhancing bidirectional lasing in single longitudinal modes in each direction. A frequency selective output coupler couples a predetermined portion of the optical energy at the lasing frequency from the ring to an output waveguide. A substantially U-shaped output waveguide having legs extending away from the ring in opposite directions and toward a common position. Clockwise and counterclockwise light waves are coupled from the ring to the two separate legs of the output waveguide and are directed to the common position to create an interfering light pattern on photodetector apparatus. The interfering light pattern is indicative of the rate of rotation, as defined by the Sagnac effect. Signal processing circuitry connected to the detector derives navigation and flight control information from the detector. In one embodiment, the ring laser and input and output couplers are implemented in a rare earth-doped lithium niobate substrate. In another embodiment, the ring laser and the input and output waveguides are implemented in rare earth-doped optical fibers. In a further embodiment, the ring laser and input and output couplers as well as the phase modulators and the photodetector apparatus are implemented in a single semiconductor substrate and gain electrically supplied to the ring laser.

摘要： An optical rate sensor apparatus (300) measures rates of angular rotation along a plurality of orthogonal axes. The apparatus (300) comprises a passive ring Sagnac interferometric arrangement having a light source circuit (308) and a series of multi-turn fiber optic rings (302, 304, 306). An optics/modulator circuit (312) selectively switches optical waves emitted from the light source circuit (308) into gyroscope channels and transmits the signals through fiber optic rings as counter-propagating optical waves. The optics/modulator circuit (312) also recombines the optical waves after they emerge from the corresponding rings. The optics/modulator circuit (312) includes optical components integrated onto an integrated optics chip (IOC) consisting substantially of lithium niobate. Optical fibers (606, 608) are coupled from the rings (302, 304, 306) to the integrated optics chip. To reduce bias error effects of reflections, the interface (610) between the optical fibers and the integrated optics chip is angled in the plane of the interferometer. Also, the angled interface (610) creates a path length difference greater than the coherence length of the reflections traversing the IOC optical paths between the interface (610) and circuitry which recombines optical waves on the IOC paths.

摘要： A control arrangement for minimizing optical leakage in a time-division, multi-stage electro-optical switch by the periodic adjustment of switching voltage levels. An optical detector connected to an idle port of the switch transmits a leakage signal which represents optical leakage in the switch in various configurations of the switch. The leakage signal is filtered by a low pass filter and sampled at a low rate. A processor stores the sampled data and periodically analyzes the data to determine the appropriate changes in the switching voltage levels for each of the stages of the switch to minimize optical leakage. An output circuit connected to the processor and the switch modifies a previously determined base voltage signals for each of the stages to incorporate the voltage level changes and applies the modified signals to the switch in the appropriate time slots.
